Dynamic mechanical characterization and modelling of polypropylene based organoclay nanocomposite

EPJ Web of Conferences, 2015
In order to investigate the dynamic behaviour of polypropylene based organoclay nanocomposite, the polypropylene matrix and a master batch of polypropylene modified anhydrid maleic were mixed by means of melt mixing technique.

New Materials for Additive Manufacturing: Thermal and Spectroscopic Analysis of pa 12–Clay Composites

Polymers for Advanced Technologies, Volume 37, Issue 5, May 2026.
ABSTRACT This study investigated the thermal and spectroscopic properties of composites produced from Polyamide 12 (PA 12) and montmorillonite (MMT) or sepiolite (SEP) clays, for application in additive manufacturing. These properties are critical during the printing process, as they directly affect the balance between the energy input to the parts and

Studies on PEBAX/organoclay nanocomposites by meltintercalation process: Effect of organoclay surface [PDF]

e-Polymers, 2009
Abstract In this study, the polyetherblock amide (PEBAX)® nanocomposites with 2.5 % and 5 wt.% organoclay, based on Cloisite 30B (montmorillonite intercalated with dimethyl, 2-ethyl hexyl hydrogenated tallow alkyl ammonium cation), were prepared by the melt-intercalation process.

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

Advanced Engineering Materials, Volume 28, Issue 7, 8 April 2026.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Surface‐Confined Nanoclays in Ethylene Butyl Acrylate Copolymer: Toward Smarter Flame Retardancy

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
This paper presents the design and characterization of nanostructured flame‐retardant systems based on ethylene–butyl acrylate and nanoclays. Two different approaches, namely bulk and surface‐coating, were exploited, comparing their effects on combustion behavior, ignition delay, and char formation.

Synergistic Effects of Reverse Kneading Blocks and Compatibilizers in a Twin‐Screw Extruder: Boosting Dispersion and Physical Properties of Recycled PP/PET

Polymers for Advanced Technologies, Volume 37, Issue 4, April 2026.
ABSTRACT Recycled polypropylene (PP)/polyethylene terephthalate (PET) blends often exhibit poor phase compatibility and suboptimal mechanical properties due to their inherent immiscibility. This study investigates the synergistic effects of reverse kneading blocks (RRK3) and chemical compatibilizers on filler dispersion, interfacial adhesion, and the ...
